Open MRI plays a pivotal role in modern healthcare by bridging the gap between diagnostic accuracy and patient-centered care. It is often the preferred imaging method for MRI patients who may feel claustrophobic in traditional MRI machine designs. Additionally, open MRI is particularly beneficial for larger patients that may not fit within closed MRI systems.
In this article, we explore what an open MRI is and discuss the key advantages to this medical imaging marvel.
What Is Open MRI?
Open MRI is a type of MRI scanner that offers a more open and less confined environment compared to traditional closed MRI scanners. Traditional MRI machines consist of a narrow tube-like structure where the patient lies down during the scan. Some patients may find this setup uncomfortable, claustrophobic, or may have difficulty fitting into the machine due to size or anxiety issues. Open MRI machines utilize strong magnetic fields and radio waves to produce detailed internal body images. These specialized scanners offer a spacious layout, benefiting claustrophobic or larger patients.
Definition of Open MRI
Open MRI earns its name due to its design featuring wider, open design configuration compared to traditional closed magnet designs. This open pillar design provides patients with a less confining and claustrophobic experience during imaging procedures. The name commonly refers to a type of magnetic resonance imaging scanner characterized by its more spacious pillared design. It provides patients with a more comfortable imaging experience. This design accommodates individuals who may experience anxiety, claustrophobia, or have difficulty fitting into traditional closed MRI machines.
Advantages of Open MRI
1. Enhanced Patient Comfort
Open MRI offers a more spacious and less restrictive environment, reducing feelings of claustrophobia and anxiety during the imaging process.

2. Accessibility for Diverse Patient Needs
Its wide enclosure design accommodates patients of various body sizes, including those who may have difficulty fitting into traditional closed MRI machines or who require additional space due to mobility issues.
3. Pediatric-Friendly Imaging
This system provides a more child-friendly setting, making it easier for pediatric patients to undergo imaging procedures without experiencing significant distress.
4. Versatile Applications
Open MRI is suitable for a wide range of imaging needs, including orthopedic, neurological, and abdominal imaging, making it a versatile tool in diagnostic medicine.
5. Accessibility for claustrophobic patients
The machine’s spacious and open design eases confinement and anxiety, enabling comfortable imaging. It ensures patients receive essential care without claustrophobia, promoting well-being and protocol compliance.
Magnet Strength and Operating Frequency
Open MRI scan machines typically operate at lower magnetic field strengths and frequencies compared to closed MRI machines. The magnetic field strength is measured in units called tesla (T). While closed MRI machines often operate at 1.5T or 3T, open MRI machines commonly range from 0.2T to 0.7T.
These lower magnetic field strengths are primarily due to the design of open MRI machines. A more open-sided configuration necessitates compromises in magnetic field strength to accommodate the larger gap between the magnet poles.
Operating frequencies in MRI machines are determined by the strength of the magnetic field and are measured in megahertz (MHz). Higher magnetic field strengths correspond to higher operating frequencies.
Closed MRI machines, operating at 1.5T or 3T, typically have operating frequencies ranging from 42 MHz to 128 MHz. In contrast, open MR imaging machines, operating at lower magnetic field strengths, have lower operating frequencies, often ranging from 5 MHz to 20 MHz.
Open MRI operates at lower magnetic field strengths and operating frequencies compared to closed MRI machines. Despite this design difference, they still provide valuable diagnostic imaging capabilities.
Open MRI vs Closed MRI
When it comes to diagnostic imaging, patients often wonder about the differences between open and closed MRI machines. While closed MRI machines provide higher magnetic field strengths and may offer better image resolution, open MRI scanners offer a more spacious and less confining environment, making them ideal for patients who experience claustrophobia or discomfort in enclosed spaces.
Understanding the distinctions between these two types of MRI machines can help patients make informed decisions about their imaging needs. Explore the comprehensive comparison between closed and open MRI machines in our detailed article.

Open MRI Design Features
Open MRI scanners are distinguished by their unique design, featuring a wider, pillared configuration compared to closed MRI machines. Instead of a narrow tube-like structure, open MR machines typically have a wider enclosure, providing patients with a more spacious and less confining environment during imaging procedures. This design allows for increased patient comfort and accessibility, particularly for individuals who may experience anxiety or claustrophobia in traditional closed MRI scanners.
In contrast, closed MRI machines enclose the patient within a tunnel-like structure, which can be unsettling for some patients, especially those prone to claustrophobia. While closed MRI scanners offer a more confined space, they may also provide slightly higher magnetic field strength and better image quality in some cases due to the closed design’s ability to minimize signal interference.

Impact on image quality
Open MR scanners may have a slightly different impact on image quality and scan times compared to closed design machines. Closed MR systems often provide higher magnetic field strengths, which can result in better image resolution and contrast, open MRI scanners may compensate for this with advanced imaging techniques and software optimization.
Diagnostic accuracy
When comparing diagnostic accuracy between open and closed MRI machines, studies have shown that both types of scanners can provide reliable and accurate imaging results for a wide range of medical conditions. While closed scanners may offer higher image resolution and signal-to-noise ratio due to their enclosed design, open systems have demonstrated comparable diagnostic accuracy in numerous clinical studies.
In many cases, open MRI scanners provide a viable alternative for patients who may find traditional MRI machines uncomfortable or challenging to tolerate, without compromising diagnostic accuracy or image quality.
Factors such as patient comfort, accessibility, and the specific imaging needs of each patient should also be considered when determining the most suitable MRI system for diagnostic imaging.
Clinical Efficacy
Often provides higher magnetic field strength, which can result in better image resolution and quality.
May offer shorter scan times due to higher magnetic field strength and optimized imaging protocols.
Can be more cost-effective for healthcare providers in terms of initial investment and maintenance.
Ultimately, the choice between open and closed MRI depends on factors such as patient comfort, imaging requirements, clinical considerations, and cost considerations. Healthcare providers will assess these factors to determine the most suitable option for each patient’s needs.
Clinical Applications
Pediatric imaging
Open MRI holds immense value in pediatric imaging, offering a less intimidating and more child-friendly environment. The spacious design of these diagnostic imaging scanners helps alleviate anxiety and claustrophobia in pediatric patients. This results in improved cooperation and better-quality imaging results. Additionally, specialized imaging protocols ensure optimal diagnostic outcomes for various pediatric conditions.
Orthopedic imaging
Orthopedic imaging benefits significantly in assessing joint and musculoskeletal conditions.
